In the context of IT support, the levels L1, L2, and L3 refer to different tiers of support, with each level responsible for providing support for different types of issues. The levels are typically organized in a hierarchy, with L1 being the first point of contact for users and L3 being the highest level of expertise.
L1 support, also known as level 1 support or front-line support, is the first level of technical support that users typically encounter. L1 support is responsible for handling basic issues and providing initial troubleshooting for more complex problems. This level of support is typically provided by IT staff or customer service representatives who have a general understanding of the system and are able to resolve common issues or escalate more complex problems to higher levels of support.
L2 support, also known as level 2 support or technical support, is the next level of support after L1. L2 support is responsible for handling more complex issues that cannot be resolved by L1 support. This level of support is typically provided by IT staff or technicians who have more specialized knowledge and expertise in a particular area or system.
L3 support, also known as level 3 support or advanced support, is the highest level of support and is responsible for handling the most complex and critical issues. L3 support is typically provided by IT staff or engineers who have a deep understanding of the system and are able to resolve issues that cannot be handled by lower levels of support.
In summary, L1, L2, and L3 support levels are tiers of technical support that are organized in a hierarchy, with L1 being the first point of contact for users and L3 being the highest level of expertise. The levels are responsible for handling different types of issues and providing support to users at different levels of complexity.
